Abstract: ABSTRACT OF THE DISCLOSURE A housing is provided defining a closed lower combustion chamber and a closed upper afterburn chamber disposed immediately above the combustion chamber with one marginal portion of the combustion chamber projecting horizontally outwardly beyond the corresponding marginal portion of the after-burn chamber.  A combined flue gas and bypass chamber is disposed above the one marginal portion of the combustion chamber and is horizontally registered with the afterburn chamber.  Partition structure divides the combined flue gas and bypass chamber into central and remote end portions spaced along the aforementioned one marginal portion and a pair of first ports communicate the remote portions with adjacent underlying upper portions of the combustion chamber, a pair of second ports communicate the remote portions with adjacent portions of the afterburn chamber and third port structure communicates the central portion of the afterburn chamber with the central portion of the combined chamber. Further, fourth port structure communicates the central portion of the afterburn chamber with an underlying central upper portion of the combustion chamber.  Catalytic combuster structure is disposed in the first ports and damper structure is operatively associated with the fourth port structure for variably opening and closing the latter. Flue gas outlet structure opens outwardly of the central portion of the combined chamber, combustion air inlet structure opens into the combustion chamber and supplemental combustion air inlet structure opens into the combustion chamber closely adjacent the combuster structure.

Abstract: ABSTRACT OF THE DISCLOSURE:         An  improved  method and apparatus for the ensonification of at least  a  portion  of  a  body  part  with  acoustic  energy  pulses is disclosed.   The present invention detects the amplitude of a resultant echo  pulse,  as  well  as  the  polarity  sense  of  the pulse at peak amplitude.   The  amplitude and polarity measurements of the echo pulse are  used  to produce color intensity throughout the body part for each individual  pixel  element  forming  a  color  display.   The  detected polarity  and  amplitude information is averaged in order to obtain the best  measure  of  color  within  each  picture  element comprising the display.   Multiple  lines  of  echo  pulse  trains are stored as image information  and  then  displayed  as a final image in a standard color television  format  thereby  resulting  in an improvement in resolution indicia  of  tissue  character.   The present invention also includes a method  for  detection  of  the  amplitude  and polarity of multi-cycle pulse  echoes  reflected  from complex media.  The improvement includes the  steps  of  integrating  each  half-wave  signal of the multi-cycle pulse   echo   and   generating   an  absolute  integral  value  signal corresponding  thereto.   A series of successive integral value signals are  then  compared to determine if a predetermined pattern among them exists.   If a predetermined pattern is detected, a peak identification signal  is  then  generated such that ultrasound echoes may be detected without de-convolutional signal processing in computation, and without the  use  of specialized acoustic pulse generators or transducers.  The invention  also  includes  an  improvement  in  a method for displaying weighted  transitions  between ultrasound pulse echoes indicative of an acoustical  interface  and  displaying  the  same on a color television display.

Abstract: Abstract A valve that directs flow from an inlet to at least two outlets, and which counterbalances flow induced forces that tend to restrict flow to one of its outlets.  The valve has a valve chamber formed in a housing, and the inlet communicates fluid to the valve chamber.  A valve member is movable in the valve chamber to communicate fluid from the inlet to the two outlets.  The valve member has a land which fluid flows across as the fluid flows from the inlet to one of the outlets, and the fluid flow across that land creates a force which acts on the valve member urging the valve member in a first direction in which flow across the land to the one outlet is restricted.  Means communicates fluid pressure from the other outlet to the valve member to apply a force to the valve member that urges the valve member in a second direction that is opposite the first direction, to counterbalance the flow induced forces on the valve member.

Abstract: Abstract of the disclosure In equipment that is intended for applying a blank of foil to bottles and that includes a turntable, at least one labeling station, a rotating transport star that has accommodations for the bottles and is positioned downstream of the turntable, and a rotating transfer-and-application device consisting of several similar units distributed around its circumference with elements that fold and press down the ends of the blank extending beyond the head of each bottle, the pressure-application elements and if necessary the folding elements are, as they revolve, kept outside the circumference of the elements on the turntable that accommodate the bottle.  This avoids collisions at this point.  The axis of rotation of the pressure-application elements and the axis of rotation of the output star are accordingly mutually eccentric in such a way that the orbits of the accommodations and of the pressure-application elements coincide along one segment.  The equipment will not malfunction and will ensure satisfactory bottle foiling.

Abstract: Abstract of the Disclosure A load-commutated inverter for operating a synchronous motor having two sets of 3-phase windings.          The difference of phase angles between the two sets of the 3-phase windings is 30 degrees.  The load-commutated inverter is provided with two sets of inverters and a control circuit.  Each of the inverters, is formed of thyristors.  The inverters are coupled respectively to the 3-phase windings of the motor.  The commutation of each of the thyristors is controlled in accordance with a given advanced control angle.  The control circuit is coupled to the inverters and is responsive to a commutation overlapping angle of currents (e.g., IU1, IV1 in Fig. 4A) supplied from the inverters to the 3-phase windings of the motor.  The control circuit adjusts the given advanced control angle so as to retain a relation: u - .gamma.* ? 30 degrees wherein u denotes the commutation overlapping angle and .gamma.* corresponds to the reverse-biasing time applied to each of the thyristors.

Abstract: A CELLULAR VIRAL INHIBITOR COMPOSITION          ABSTRACT         A composition for the treatment and prophylaxis of viral infections in mammals is provided.  The composition includes an amount of a contact-blocking viral inhibitor (CVI) in a diluent sufficient to elevate the concentration of the viral inhibitor in a mammal's tissue above the naturally occurring concentration in that same tissue.  Methods for purifying and concentrating CVI are presented.  The cellular viral inhibitor is characterized by broad antiviral activity, potency, reversible inhibition of viral attachment, cross species activity and molecular size.  Natural levels of CVI range from 6 U/0.1 ml in tears to 400 U/0.1 ml in gastric secretions, with titers between these ranges found in colostrum, milk, plasma, saliva and urine.  Biochemical characterization of the CVI indicates that it resists denaturation by heat, acid and alkali, and it exhibits a molecular size on the order of 2500 daltons.
